4.5 Stars out of 5
- by 13xforever, a year agoRated 4 out of 5Great little indicator. One inherent issue is it fails to indicate anything on tab restore (which happens all the time when you restart the browser for example)
- by Firefox user 14357202, a year agoRated 5 out of 5Very nice and clean add-on which is used daily to troubleshoot loadbalancing issues. I'm still happily waiting for the copy functionality. :)
- by Firefox user 15204090, a year agoRated 4 out of 5Useful to give all IP connections of a site.
*** What do the coloured icons mean?? Green, blue, copper. Does C mean combined? ***
Developer responseposted a year agoHi there. Green = IPv6 used to connect, but both IPv6 and IPv4 addresses listed in DNS, blue is IPv6 only, red IPv4 only, and yellow/orange means IPv4 was used to connect but there are AAAA (IPv6) records in DNS for the host. The C means the request was cached (i.e. no network request was made to load that bit of the page).
I've updated the documentation page too - http://ashley.baldock.me/sixornot :)
- by Firefox user 13029084, 2 years agoRated 2 out of 5I was glad to see the return of SixOrNot, but version 3.1.2 often presents a black pop-up when clicking on the icon instead of a readable pop-up.
This is on Nightly 64.0a1 (2018-09-12) (64-bit) on Windows 10 (64-bit). I also have IPvFoo installed and have been comparing the results of both.
- by imcdona, 2 years agoRated 5 out of 5Excellent plugin! Displays not only the protocol used for the hostname in your address bar, it also displays the protocol used for each individual resource downloaded on a given page.
- by Firefox user 14086830, 2 years agoRated 3 out of 5Good work! It would be even better with a couple tweaks:
1. Mark the standard DNS64 64:ff9b::/96 range as IPv4 (since the end resource is really IPv4, it's just translating the 'synthetic' IPv6 prefix to IPv4 at the NAT64 box).
2. Enable copy/paste of the address/host output from the gui, in text format.
3. Make a distinction between the base domain 4/6 status vs the 4/6 status of the other domains called by the site. IPvFoo does this with a large 4 or 6 for the main domain and small 4 and/or 6 for the trackers and other domains that a site may load.
- by TommyTek, 3 years agoRated 5 out of 5For those of us that like to see the progress of IPv6, this tool is wonderful. It's also a quick and dirty way to see many of the sites that are accessed when you think you're only on one URL. Ashley's 3.0.0 version actually appears to mostly work on Firefox 58.0.2 as well as the 59.0 release candidate. Thanks for not giving up on this add-on Ashley!
- by Firefox user 13224295, 3 years agoRated 5 out of 5Hope a webextension version will be available soon.Sadly it's unlikely. Mozilla haven't provided webextension APIs to do DNS resolution, without which all I could really do is duplicate IPvFoo. I don't really have the heart to throw away most of what Sixornot does. It'll die with FF56.
- by CypherOz, 3 years agoRated 5 out of 5E10s will kill this by November 17 if no action is taken. Sad that this should be. Great add-on much needed.Hi CypherOz - SixOrNot has had E10S support for quite a while now, since 2015 with version 2 :)
Edit: I hadn't realised Mozilla are removing "legacy" addon support so soon. A WebExtension version of SixOrNot is definitely possible although it'll lose the ability to do OS-native DNS queries. I guess I'll start rewriting it for the fifth time...
Edit 2: So there's no way of doing DNS lookups from a WebExtension addon. You also can't get proxy information (or TLS information, although this may change) for web requests. So migrating would involve the loss of over half the current functionality. I remember when Firefox used to be all about the addons...
- by Firefox user 12991026, 4 years agoRated 3 out of 5After using it I disabled it so I could keep it around without adding clutter to my browser. Unfortunately it comes back when I restart my browser so I'll uninstall.
edit: on Ubuntu Gnome 17.04, latest FF at time of writing (normal update track. currently at 53.0.3 x64)
- by Faidon, 4 years agoRated 5 out of 5This plugin is super useful, nice work! I like how the latest versions show the TLS status per each origin as well, that's pretty neat.
It'd be nice if it could also show SPDY or HTTP/2 status. There is a separate plugin (with nice icons!) called "HTTP/2 and SPDY indicator" but it's unmaintained and could UX-wise it would make sense for SixOrNot to incorporate this kind of functionality.
- by Bret Schmerker, 4 years agoRated 5 out of 5This WebExtension pinpoints all IP addresses used on any World Wide Web page, on the client station as well as the server points across the Internet; once the addresses are known for a suspicious site, the security specialist can narrow down ports used for each. Only bug I've seen is in display of IPv6 addresses, which need four digits hexadecimal for each of the eight numbers; as of 28 November 2016 this Extension truncates the highest zero(s) (one digit below 0x10, two below 0x100, &c.). All IPv4 addresses, and backing functionality, work as advertised.
- by reza, 5 years agoRated 4 out of 5when I use the nslookup command in my linx machine I get only ip4 address of domain but your addon shows ipv6 too for some addons . how is that possible?
I said it wrong.
I meant that your addon description says that it doesn't do anything just uses my system provided info to show the ips that I am connecting to for each domain.
but now you are saying that it forces my system dns to also check to see if they have ipv6?
for example I have disabled the ipv6 on my system.
and I use your addon to see which domain uses which ip.and which one is connecting via proxy.( I have a lot of those).
so for each domain that I am connecting you addon makes a ipv6 check via dns?
Developer responseposted 5 years agoEdit:
SixOrNot doesn't query an external service to, for example, find out your external IP address or perform DNS queries - but it does make use of your local system's DNS resolution mechanism to perform a DNS query for each domain visited. This is used to display the yellow/blue icons (showing whether IPv6 is available and not being used, or if a site can only be contacted by IPv6). Typically this DNS query is serviced from the local cache (since your web browser will have very recently performed the same query to connect to the page) though in the case of cached pages, or where IPv6 has been disabled it's possible that this will result in additional DNS queries going "across the wire".
The queries are all handled asynchronously by the addon and so shouldn't have any performance impact (especially in the latest multiprocess versions of Firefox with electrolysis enabled). Also, DNS queries are only performed for the "main" domain contacted as a matter of course (this is used to update the main icon UI when the information panel isn't displayed). DNS queries are only performed for the "secondary" domains contacted to load the page when the panel is opened. This was a change from v1 (which did the DNS lookups at the time when the connections were made) which was necessitated by the change in addon architecture to support electrolysis/multiprocess.
(It's also probably worth pointing out that the addon (v2+) doesn't perform DNS resolution for connections that are made via HTTP/HTTPS proxies, or SOCKS proxies where the proxy handles DNS resolution - this is to avoid leaking information about connections made over proxies via DNS queries)
It wouldn't be too hard to provide a preference to disable the DNS resolution feature for your use case though if you're concerned by the extra network traffic. Originally the whole point of this addon was to provide info about IPv6 availability, but I can see that there's a definite use case for just seeing the IP addresses/proxy info/SSL info now. I'll see about adding a preference for the next release and updating the description so it's clearer exactly what the network traffic impact of the addon may be.
nslookup defaults to retrieving A records for a domain (A records are for IPv4 addresses) - you can get nslookup to retrieve AAAA records (the IPv6 equivalent of A records) with the "-query=AAAA" flag - e.g. "nslookup -query=AAAA google.com".
- by David, 5 years agoRated 5 out of 5When used with ClassicThemeRestorer, with the stop/reload button in the location bar removed, the icon that this places in the location bar ends up jammed against the edge of the location bar box.
Otherwise, nice that it's working again with e10s.
- by Alpengreis, 5 years agoRated 5 out of 5I do not use the Fx Dev version right now. However: future regular versions of Fx will have E10s and the developer has added now the support for this already - GREAT!
- by afilios, 6 years agoRated 4 out of 5Not working on Firefox Nightly x64. Can you fix it?
On other Firefox versions, excellent!
-- what OS are you seeing the problem on?
Windows x64 (7 & 8.1). Thanks
- by Firefox user 6099093, 6 years agoRated 5 out of 5This is a great tool for checking whether CDNs and other dependencies like ad providers and analytics tools are v6-enabled.
Working fine here on 32.0b on OS X 10.9.
